FilmQueryProject

Film Query Lab and Homework Project!

Technologies Used

- JAVA
- Eclipse
- Git/GitHub
- Sublime Text Editor
- Zsh
- MySQL
- DAO, JDBC
- JUnit Tests

Lessons Learned

- Using a shared connection at the DatabaseAccessorObject.
- Protecting against too many open connections.
- Need for more abstraction and shared code.

Notes

JUnit test(s) have been implemented for retrieval and compare the results as if the DB was freshly created and populated with the starting data.

This means, for actorId = 1, there are 19 films that are retrieved.

	@Test
	void test_getFilmsForActorId_returns_19_for_id_one() {
		List<Film> films = db.findFilmsByActorId(1);
		assertEquals(19, films.size());
	}

This also means that the results for getting actorId = 2 is as follows.

• id=2
• firstName=Nick
• lastName=Wahlberg

	@Test
	void test_getActorById_returns_actor_with_id() {
		Actor a = db.findActorById(2);

		// id=2
		// firstName=Nick
		// lastName=Wahlberg

		assertAll("Actor", () -> assertEquals(2, a.getId()), () -> assertEquals("Nick", a.getFirstName()),
				() -> assertEquals("Wahlberg", a.getLastName()));

	}

User Stories

User Stories

User Story 1 (COMPLETED)

The user is presented with a menu in which they can choose to:

• Look up a film by its id.
• Look up a film by a search keyword.
• Exit the application.

User Story 2 (COMPLETED)

• If the user looks up a film by id, they are prompted to enter the film id. If the film is not found, they see a message saying so. If the film is found, its title, year, rating, and description are displayed.

User Story 3 (COMPLETED)

• If the user looks up a film by search keyword, they are prompted to enter it. If no matching films are found, they see a message saying so. Otherwise, they see a list of films for which the search term was found anywhere in the title or description, with each film displayed exactly as it is for User Story 2.

User Story 4 (COMPLETED)

• When a film is displayed, its language (English,Japanese, etc.) is displayed, in addition to the film's title, year, rating, and description.

User Story 5 (COMPLETED)

• When a film is displayed, the list of actors in its cast is displayed, in addition to the film's title, year, rating, description, and language.

Stretch Goals

Goal 1

• When a film is displayed, the user can choose from a submenu whether to:

• Return to the main menu.

• View all film details.

• If they choose to view all details, they will see all column values of the film record they chose.

Goal 2

• When viewing film details, the user will see a list of all the film's categories (Family, Comedy, etc.) for the film.

Goal 3

• When viewing film details, the user will see a list of all copies of the film in inventory, with their condition.

Goal 4 (COMPLETED)

• Write JUnit tests for DatabaseAccessorObject's methods.
